COMBINED POLE AND SHAFTS FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 336,334, dated February 16, 1886.

Application filed August 21, 1885. Serial No. 175,003. (No model.)

To all whom it may concern:

Be it known that I, AARON JEFFERSON MARTIN, a citizen ofthe United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Improvement in Combined Pole and Shafts, of which the following is a description.

This invention is an improved draft attachment for vehicles, whereby the same draft devices may be adjusted for use with a double or a single team, as may be desired.

By my invention I make one construction answer the purpose of a pole or tongue and shafts and providea simple construction by which the parts may be readily adjusted for either purpose.

In the drawings Figure 1 is a perspective view of the improvement with the draft-seotions adjusted for use as a pole or tongue. Fig. 2 is a plan view of the improvement with the draft-section shown adjusted for a single team and with the arrangement of Fig. l indicated in dotted lines. Fig. 3 is a detached section on linear x, Fig. 2; and Fig. 4 represents in detaila modification of the fastening devices.

The crossbar A may have arms A or be secured to the vehicle in other suitable manner. Each draft-section B has at its rear end a right-angled arm,B. These arms are pivoted at O, centrally between their ends, to the cross-bar and at equal distance on opposite sides of the center of the cross-bar. These arms t flush against the crossbar and may be turned on the pivots to adj ust them to either the position shown in Fig. l or that shown in Fig. 2. The outer ends of the arms meet at the center of the cross-bar when the device is adjusted for a single team, and their inner ends meet at the same point in the reverse position of the pair. By pivoting the arms to the front edge of the crossbar, the cross-bar and arms may be rested within the same plane and a neat simple construction is provided. On the cross-bar is pivoted the tree D, which may be a single or double tree, according to whether the draft-sections are adj usted for use with a single or double team.

As a fastening I provide the triplearmed clip E and the pivot-bolt or hammer F. The

clip has arms e, e', and e2, each of which isperforated to receive the pivot-bolt. The arm e rests under the cross-bar, the arm e between the crossvbar and tree, and the arm e'l overthe tree. The pivot-bolt passes dow n through the clip, the tree. and the crossbar, and sccures such. parts trmly together.

Instead ot' the form of fastening shown in Figs. l, 2, and 3, that shown in Fig. 4, may be used. This consists of a clamp, G, having a top plate, g, and hook-like wings g. The rear end of plate g is notched at g, and the clip H tits into such notch and has its arms perforated for the pivot-pin. A sleeve or thimble, I, is provided to lit on the front ends of the sections when the latter are adjusted for use as a pole.

Having thus described my invention, what I claim as new isl. The combination of the cross-bar, the draft-sections having rightangled arms at their rear ends, horizontal pivots connecting such arms to the crossbar midway their ends, whereby said arms may turn in a vertical plane, and a clamp arranged and constructed to engage the inner ends of said arms when the draft-sections are adjusted for use as a pole and the outer ends of said arms when the sections are adjusted for use as thills, subst-an` tially as set forth.

2. The combination of the cross-bar and the draft-sections having at their rear ends right-angled arms, and pivots connecting said arms to the cross-bar, such pivots being located midway the ends ofthe arms and at points equidistant from the center of the crossbar, and adistance apart equal the length of one ot the arms, whereby the innerends of said arms will abut when such sections are adjusted for use as a pole, and their outer ends will abut when the sections are adj usted for use as thills, and a clamp whereby to engage the abutting ends of the arms and connect same to the cross-bar in the different adjustments of the sections, substantially as and for the purposes specified.

AARON JEFFERSON MARTIN.
